Abstract

Abstract

In order to improve the performance of vector propulsion motors in deep-sea exploration, this paper proposes a control method for deep-sea vector propulsion motors based on the surface-mounted permanent magnet synchronous motors , combined with Periodic Carrier Frequency Modulation (PCFM) technology and improved Sliding Mode Observer (SMO) position-sensorless control technology.Through simulations of motor carrier frequency variation, motor start-up speed variation, and load disturbance, this paper analyses the simulation results of the proposed control method. The results show that the speed estimation of the studied control method is accurate and has good dynamic tracking performance. The error rate at the rated rotation speed is only 0.32%, and the error rate at 0.5 times the rated rotation speed is only 0.09%.Besides, the proposed control method has obvious high frequency harmonic expansion frequency suppression effect and good dynamic anti-interference performance.Combined with the simplification effect of reducing the motor structure brought by the position sensor, the control method proposed in this paper can effectively reduce the failure rate of the deep-sea vector propulsion motor operation, reduce the high-order fixed frequency harmonics that are easy to be detected,improve the reliability of the deep sea vector propulsion motor and stealth, provide efficient and reliable guarantee for deep sea UUV.
